Pilot Desalitech SWRO commercial plant.

Doing away with RO energy-recovery devices

Energy-recovery devices have been a crucial element in the reduction of the cost of desalination during the past decade, bringing the technology within reach of conventional water resources costs in certain circumstances. Typical energy consumption for seawater reverse osmosis (SWRO) is now around 2.5 kWh/m . Desalitech's Closed Circuit Desalination, which does away with an energy-recovery device, reports energy consumption for SWRO of 1.65-1.87 kWh/m . This article was first published in the August/September 2010 issue of Desalination & Water Reuse magazine.

Depth Exposed Membrane for Water Extraction (DEMWAX™)

DXV Water Technologies has designed a novel membrane system that uses natural pressure, a very low recovery rate and gravity flow of feedwater past the membrane surface, resulting in an elegant, efficient system. Since the invention of the reverse-osmosis (RO) membrane researchers have tried to harness natural water-pressure, but past attempts mimic onshore processes with their configuration, recovery and flux. This low-flux low-recovery process will require more membrane than traditional systems; however, the elimination of intakes, outfalls, pre-treatment, pressure vessels and piping, energy recovery devices and coastal land will result in a water cost that is below many traditional sources. In addition to substantial energy savings, environmental and economic benefits that the DEMWAX system offers include: Mitigation of 'Brine' Disposal - the extremely low-recovery operation results in 'brine' at approximately 2-3% more concentrated than the surrounding ocean. Mitigation of Impingement and Entrainment - the intake velocity is several orders of magnitude less than typical intakes, virtually eliminating impingement and entrainment. Scalability - the system can be readily expan ded with the addition of cartridges and pumps. This article was published in the May/June 2009 issue of Desalination & Water Reuse.
